Abstract (en)

[origin: EP0675490A1] A method for reducing rotational latency in a system employing a rotating medium (10) includes dividing the medium into discrete angular regions (N=0...N=9), building a seek range array corresponding to the discrete angular regions, searching a command queue array for a command, executing the command and removing the executed command from the command queue array. In this manner, commands within the shortest access time of a current position (Y1) of a data retrieval element (12) are executed. <IMAGE>
